HEEL-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 393,104, dated November 20, 1888.

Application filed June 25, 1888. Serial No. 278,146. (No model.)

To aZZ whom it 12mg concern.-

Be it known that I, CHARLES W. GLIDDEN, of Lynn, in the county of Essex and State of Massachusetts, have invented an Improvement in Heel-Making Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention is intended as an improvement on the machine described in United States Patent No. 105,030, dated July 5, 1870, and has for its object to render the machine so improved more efficient for the work intended.

In the machine to be herein described the dies are open at both ends. The plunger which acts to compress the heel in the die acts directly upon the heels. The awl-holding plate and the driver-plate are fitted into the stamp so as to be readily slid in and out of position. The awls have cooperating with them a shipper-plate which is arrested as the stamp rises. The driver-plate is made adjustable vertically with relation to the stamp carrying it, and the driver-plate has co-operating with it a nailreceiver, into which nails are discharged from a loader in usual manner when the driverplate is elevated.

The especial features above enumerated as having been added to the machine referred to will be made the subject of claims at the end of this specification.

Figure l is a top or plan view of a machine embodying my improvements; Fig. 2, a righthand side elevation thereof; Fig.3, a top or plan view of the die carrying cylinder or holder detached, together with the dies. Fig. 4 is a detail of the driver-plate, drivers, and nail-receiver; and Fig. 5, a detail to be referred to.

The bed A, its legs A, upright A strengthening-web a, hanging support Z, treadle T, spring T receiving-table IV for the heel-blank to. be treated, the slide W, having the fork W", the follower-block F, to lift the heel-blank into the dies to be described, the lever V to operate it, the main shaft L, fly-wheel N, pinion L, gear K, ratchet-wheel K, dog P, spring Q,

swinging lever or stud S, rod in, tripping-lever Z, intermittingly-rotating cylinder or dieholder D, having openings or chambers for the dies to be described, the shaft J, stampplunger B, stamp or head B at its lower end, and faceplate I, are all substantially as in the patent referred to, where the like parts are designated by like letters.

Herein the dies b, carried by the cylinder or die-holder D, are made open at both ends, thus greatly cheapening the cost of their manufacture and enabling the tread end of the heelblank to be acted upon directly by the presser b, to be described, and to be freely entered by the awls, and especially by omitting the usual top to the dies various priokings may be employed with the same die.

The presser b has its shank threaded, as at b and is screwed into a part of the stamp or head 13', so that the presser may be adjusted vertically with relation to the said stamp or head which actuates it, in order that the presser may have just the desired extent of throw to strike the tread end of the heel and force it down level with the top of the cylinder or holder D.

The pricking-awls 2 (any desired number) are arranged, as usual, in the awl-carrier plate 3, the latter in accordance with my invention having its edges dovetailed or flanged .to slide longitudinally out and in a groove of corresponding shape made in the stamp or head B, as shown in Fig. 2, so that the said plate is readily removable when it is desired to intro duce a plate having the awls differently ar' ranged for a different pricking. Aset-screw, 4, holds the plate 3 in place. The plate has rising from it a-socket, d, which receives in it the shank d of the stripper (1, through which the awls pass as they enter the heel to prick it. As the stamp or head rises to withdraw the awls, the upper end of the shank d meets the adjustable stop 5, made as a screw screwed into a lug, e, fixed to the frame-work, and is arrested thereby, so that the stripper stands while the awls continue to rise and are withdrawn from the heel-blank.

The tripping-lever Z at its inner end has pivoted on it the usual stopping-dog, 12, for holding the cylinder D and dies 1) in position 7 in the descent of the stamp.

The pivot 13, on which the dog 12 turns, is in my present invention extended upward, as

IcO

shown by dotted lines, Fig. 2, and receives upon it a rocker-lever consisting of a sleeve having an arm,f, of substantially the same shape as the end of the dog under it, and an arm or lug, f. (Best shown in the detail, Fig. 5.)

The latch g, by which tomove the cylinder 1), it having a point to enter suitable notches in the said cylinder and having a handle by which to move it, has an arc-shaped shoe, 8, (see Fig. 2,) which enters a groove, 16, made in the bed'A. This latch g has upon it an ear, upon which is pivoted a latch, 17, the inner end of which is beveled, as best shown in Fig. 1, to act upon the arm f of the rockerlever referred to as the latch g is moved fully to the right after having been moved in the opposite direction to effect the change of position of the dies, as provided for in the said patent.

If it is not desired to release the slide-frame from the catch 21, then the latch 17 will be turned so as not to strike the arm f.

The stamp has a projection, 71, (see Figs. 2 and 4,) provided with guides h, in which slide the slide-rods h", forming part of a frame, h, to the lower end of which is secured the perl'orated nail-receiver h", which receiver, when the parts are as in Figs. 2 and 4, is adjusted to be filled with nails from a perforated nailfeeding block having a thin but movable bottom plate, as provided for in the said patent. The upper portion, h", of the slide-frame enters a sleeve-like guide, h, suitably attached to and rising and falling with the plunger 13, the said guide having within it a spring, 20, to normally throw the slide-frame down in the position Fig. 1- whenever the latch 21 is released from the head 19 of the said slideframe, which is done whenever the latch 17 strikes the arm f, for then the socket shaft or sleeve to which the said arm is attached is turned sufficient] y to cause the arm 1'' to meet the arm 24-, attached to the rock-shaft 22, carrying the latch 21, the said rock-shaft having its bearing in a sleeve, 23, fixed to the stamp 13.

The latch 21 is normally acted upon'by a spring, 25, so that when the stamp is depressed the latch will catch under the head 19, ready to lift the said nail-receiver when the stamp next rises, the lifting of the stamp and receiver permitting the cylinder and dies to be turned in usual manner.

The projection h referred to is slotted at m to receive a nut, m, into which is screwed the shank of the carrier m which is slotted or dovetailed to receive in it the dovetailed or flanged driver-plate m, provided with drivers m", the said plate being inserted in the carrier, as described, so that it may readily be withdrawn when it is desired to place in the carrier a plate having driversarranged to accommodate for a different pricking, the nail-receiver being also changeable.

In operation the heel blank to be compressed, pricked,and loaded with nails will be moved by the fork W into position immediately above the follower-block F, when the operator, by the lever V,will raise the follower and blank into that one of the dies which is directly over the follower-block, and then the operator will turn the cylinder or die-carrier Donestep,bringing the said follower and die the latter at that time being somewhat raised in the die-holder and having a blank partially driven into itunder the presser,the dieholder being stopped with the follower directly over a spring bed piece supported upon a strong spring, the said bed-piece and spring -not, however, being herein shown, because they are common to the said patent. With the die containing the blank in the position described, the stamp is thrown down, causing the presser to first act upon the elevated die containing the blank, the latter resting upon the follower, in turn resting upon the bedpiece, as stated, and presses the die down over upon and so as to compress the heel and force the latter into the die, the compression being continued until the upper end of the die and the tread end of the heel are brought into the same plane, and the die is forced down into its seat into the cylinder or die-holder, the fol lower within the die--as the die is brought down to its seat-acting to for m a concavity in the seat end of the heel, as in the patent referred to. The heel having been compressed and the stamp lil'ted,theope rator will give the cylinder another quarter turn, bringing the compressed heelunder the awls, which,as the stamp again descends, prick the heel at the desired points. The heel having been pricked, the stamp will be lifted, and as the stamp is lifted the shank d of the stripper meets the stop 5, arresting the upward movement of the stripper d and permitting the awls d to be drawn from the heels. During this latter operation the awls act to somewhat lift the die from the cylinder or die-holder; but, the awls having been completely withdrawn, the die drops back into its posit-ion,and the die-holder is again moved a quarter-turn until the pricked blank is brought into position under the nailreceiver, and as the operator moves the catch 9 back, as described, the latch 21 is operated to permit the nail-receiver to descend upon the pricked blank. The operator then,in usual manner, supplies the receiver with nails, and the stamp is again thrown down, causing the drivers at carried by them to strike the ends of the nails then held in the receiver and drive them into the heel, after which the stamp is again raised, as described, and the cylinder is again rotated a quarter-turn,bringing the heel back into the position that it occupied when it was lifted into the die, when the said heel is discharged, as in the said patent, and another blank is inserted.

In the patent referred to, by reason of the die being closed at one end, great expense was entailed whenever it was desired to manufae- 1 ture heel-blanks with different priekings, for then an entirely new die had to be made.

I am aware that the construction of said dies was subsequen tly'improved by casting into one end of the die a steel plate; but even with that form of die a new die had to be made for each pricking.

By leaving both ends of the die open it is possible to change the position of the awls and of the drivers to correspond with them according to any desired pricking, and the said awls will descend through the open bed of the die into the blank, the plates carrying the awls and drivers being readily changeable on the machine.
